When embarking on your initial research, consider whether it covers several disciplines. If it does, ask yourself the following questions:
If your research doesn't cover multiple disciplines, consider:
It will be easier to get started if you think about how your research connects to a wider audience/research group. Other professions may approach the same area/s you are interested in from a different viewpoint and may use different search terms and phrases to the ones you may initially think of.
To help you to get the most out of this guide, you may find it useful to explore the following online resources. This set of online resources will demonstrate the process of performing a search on a number of database platforms. Click on the image below to access the resource:
This short online resource will highlight some of the common pitfalls with using Boolean logic to help you to avoid them in your own searches.

It depends on your research topic. Some areas may be rich in resources in just one or two databases. However, for most detailed research projects such as systematic reviews you may need to scout around a bit, especially if your research is focusing on a new area of development.
Each database has its own strengths and weaknesses so you will need to experiment to find the best one for your topic. Some of the smaller database platforms have more limited functionality compared with the larger platforms, however the topic coverage may be very strong. In this case you need to be clear what you are looking for before using the database.
Most databases focus on a particular subject area such as medicine or law; you need to be aware of this if you are looking at an area spans across several disciplines. For example, if you are looking at the impact of long-term sectioning of a patient with mental health issues on the patient and their families, your search concepts will include mental health, social issues, human rights and law, so you will need to use health, law and sociology databases to consider all of these areas. The key databases for each discipline are listed on the Library’s subject pages.
There will always be a degree of duplication of results across databases. Abstracts are not unique to specific databases just as groceries are not unique to particular supermarkets. There will be some unique articles in a database just as there are some unique (own brand?) groceries in supermarkets.
Different databases have different target audiences in mind, and the information within these databases is indexed according to its audience’s needs. For example PsycInfo is a psychology-focused database, so you would find more sub-categories relating to “attitude” than you would on Medline which is a more general index of mental health issues.
Cross-searching databases is a useful method of getting an overview of what literature is available, but you cannot drill down to the finer details.
For example, consider a search related to the attitude of health personnel towards patients who were terminally ill. If you searched Medline and PsycInfo together, the results from the two databases would merged and it would be difficult to separate them. This could be important because Medline results may be more focussed on keeping the terminally patient pain-free, whereas results from PsycInfo may be more focused on palliative and pastoral care.
For a systematic review, you will also need to be able to demonstrate which parts of your research fared well (or not so well) within specific results. Searching across multiple databases at once makes it much harder to do this; if you get a lot of results, it is difficult to work out which terms yield the most results.
Many of the platforms have very similar features, but different platforms will present information in different ways.
Ovid and EBSCO are the most similar of the health sciences platforms. They also have the most comprehensive tools to help you find alternative words or phrases for your search concepts (these being MeSH and the Suggest Subject Terms respectively). It can be helpful to start with these platforms to help you to identify alternative search terms; you can them use these extra terms in other databases that do not offer the same facility.
It is important to look at smaller databases that don’t have the same level of functionality; with a little thought you can usually replicate your searches on these databases.
If you retain manageable segments within your search histories, these should be more easily replicated in other resources.
Ovid, EBSCO and ProQuest are platforms that each host a number of databases; it is more accurate to refer to the specific database. Some databases such as MEDLINE are available through several platforms, so it is also helpful to include details of which platform you’ve used to make it easy to replicate your search.
You can’t. Things will always slip through the net and no database is 100% perfect. However, it is in your interests to try and obtain as much information as you can to ensure that your research is as comprehensive as possible. This may include searching relevant websites and grey literature in addition to standard database resources. When using sources like these, you need to be particularly careful to evaluate the information to ensure it’s of a high quality. Click here to learn more about evaluating your information.
Yes, using reference management software such as EndNote.
The Library runs EndNote workshops throughout the year, and we also have online support. Check out the referencing guide for more information.
The Boolean operators AND, OR and NOT are common across search tools including databases and online search engines; they are used to group search concepts together.
Incorrect use of these operators are the most common cause of errors in searches, from basic formative searches to advanced systematic review searching. Be very careful with your search strings and ensure there are no discrepancies in meanings/definitions in your batches of terms. Check out the Revisting Boolen resource for more information.
Truncation allows you to search for different variations on the same word but replacing the final characters of a word with a symbol. For example, searching for universit* would find both university and universities.
Wildcards allow you to search for multiple variations of a word at once by substituting one or more characters with a symbol. For example, searching for wom#n would find both woman and women.
The asterisk (*) has become the most common truncation symbol used at the end of a root term for most databases For example - medic* = medic, medication/s medical/s, medically, medicine/s etc..
However, there are differences across platforms in which symbols are used for wildcards and truncation, so it is important that you use the correct ones for the platform you are using.
It is important to check which database platforms use which symbols. Guidance on Truncation and Wildcard can usually be found in the database platform’s help pages.
If there are any variants in these symbols present in your search tables or search histories, it is advisable that you indicate this to ensure that there is no doubt over their correct usage.
